... formed in terrestrial and extraterrestrial environments is provided in Appendix Figure 1 in the Supplementary Materials 1 . The goals of the present study are threefold: (1) to provide an overview of terrestrial and extraterrestrial djerfisherite occurrences in the context of new data from...

... material from the Earth and impact was thrown out into the area of the Moon’s orbit. Fragments of the silicate rocks of the Earth’s mantle and impact served as a basis for the formation of the Moon’s body. The lunar rocks are depleted in siderophile elements, whose large amount was concentrated in the core...

... originated at a depth of 700 km as a result of that giant impact where there was a portioning of iron and silicate. The molten metal sank in droplets to the ocean’s bottom ( Wood, 2011 ), forming large lens-like accumulations which due to higher density descended to the mantle’s bottom and then to the core...

...M.I. Kuzmin; V.V. Yarmolyuk; A.B. Kotov; N.A. Goryachev Abstract The paper is focused on the evolution of the Earth starting with the planetary accretion and differentiation of the primordial material (similar in composition to CI chondrites) into the core and mantle and the formation of the Moon...

... and extraterrestrial processes. To shed light on question of zircon survival in the Earth's shallow asthenosphere, high-temperature experiments of zircon dissolution in natural mid-ocean ridge basaltic (MORB) and synthetic haplobasaltic melts have been performed at temperatures of 1250–1300 °C and pressures from 0.1...

We are grateful to (in alphabetical order) Andrej Arzamastsev, Sven Dahlgren, Attila Demény, Alexey Goncharov, Emma Humphreys-Williams, Jurgis Klaudius...

..., sometimes called Hadean or “hell-like,” in which any crust was destroyed by meteorite impact or melting, all water was vaporized, and the atmosphere was steam rich (see Pollack, 1997 ). The only terrestrial materials that are known to be older than 4 Ga are detrital and xenocrystic zircons from...

..., space group R 3 c to R 3 . Hemleyite was formed in a meteorite exposed to high pressures (<20 GPa) and temperatures (<2000 °C) during impact-induced shocks. That indicates the mineral could play a crucial role at the bottom of the Earth's mantle transition zone and within the uppermost lower...

... and Hsu 2018 ; Wu and Hsu 2019 ). Apatite occurs in ordinary chondrites as: (1) discrete grains with subhedral-anhedral habit; (2) grains associated with vein-filling material or impact melt pockets; (3) intergrowths with merrillite where apatite seems to have replaced merrillite; or (4) anhedral...

... of plagioclase. The O isotope compositions of apatite are listed in Online Material 1 Table OM2 and plotted in Figure 6 . Both the apatite core and rim domains have mantle-like O isotopic compositions regardless of their difference in ΣREE ( Fig. 6 ). The core domains have δ 18 O values ranging from 5.3...

... provides new evidences for the common occurrences of these unusual minerals in ophiolitic peridotites and chromitites. This discovery also suggests that deep mantle processes and materials have been involved in the formation of podiform chromitite. * E-mail: yangjsui@163.com 10 5 2016 23...

Recent work has favored formation at mantle conditions, likely in the presence of a C-O-H fluid...

... on the microstructure of extraterrestrial apatite (i.e., Słaby et al. 2017 ; Birski et al. 2019 ) have demonstrated that micro- and nanostructural examination of apatite has the potential to provide constraints on conditions of crystallization, precipitation, and fluid interaction of a magmatic source. Furthermore...

They also hypothesized that material subject to such conditions might be depleted in volatile elements relative to the Earth.

In total of the order of a few × 10 4 tonnes of low-density (0.3 g cm −3 ) comet material was released by DEEP IMPACT and much of this was dust of solar system and, possibly, interstellar origin. The initial mission results were published in 2005 ( A’Hearn et al. , 2005 ) and in the 2006 Lunar...

We tabulate 90 igneous differentiated asteroidal minerals, including...

Further evidence for widespread processing of the mantle comes from Nd-Hf isotope studies ( Blichert-Toft and Albarède 1997 ). In a plot of 143 Nd/ 144 Nd vs 176 Hf/ 177 Hf, mantle values lie...

Lower values for the mantle are due to radiogenic He production. Unfortunately, due to the ubiquity of parent U and Th, initially trapped and subsequently unaltered He...
